Helicopter torque

Recommended Posts

There are some brilliant people on here that I would like to ask a question. In a hover auto show r simulated stuck right power approach what makes us yaw left when we roll off throttle? Thanks so much!

35 people were just reading this, but no one responded, so I guess I'll take a whack at it. Even with a stuck right pedal the tail rotor is still producing anti-torque thrust (just not enough to keep the nose straight) so when you roll down the throttle main rotor torque is reduced, which in turn reduces the amount of anti-torque you need, so the nose yaws left.

Too much left pedal applied following the throttle chop or lack of right pedal, #1 common error. Moreover, just too much positive tail rotor pitch remaining vs. the level of torque.

 

Power Failure in a Hover, Common Errors:

 

1. Failure to use sufficient proper anti-torque pedal when power is reduced.

 

2. Failure to stop all sideward or backward movement prior to touchdown.

 

3. Failure to apply up-collective pitch properly, resulting in a hard touchdown.

 

4. Failure to touch down in a level attitude.

 

5. Failure to roll the throttle completely to idle.

 

6. Failure to hover at a safe altitude for the helicopter type, atmospheric conditions, and the level of training/ proficiency of the pilot.

 

7. Failure to go around if not within limits and specified criteria for safe autorotation.

Going round from a hovering engine failure, I like that!
